(01. ir s- 2) Fig. 8 is a fragmentary sectional view taken on line 8-8 of Fig. 4. i Referring to the drawings in general, there 1 shown a furnace 20, the front wall 21 of which is provided with an opening 22 for receiving the burner part of the fuel burning apparatus 24 (see Figs. 2 and 3). The fuel burning appa ratus includes supporting base 25 which carries a motor 26 which drives a fan inclosed withina housing 27 and a rotary fuel burner inclosed within the casing 28. An upwardly extending flange-30 of the base 25 carries a cover 31 of suitable heat resisting material such 'as asbestos which is arranged to close the opening 22 in the furnace when the apparatus is in position as shown'inFig.2. Y It is desirable that the enlarged'head portion of the burner 28 be disposed at a lower level and therefore the burning apparatus is adjacent the sill 32'of the door opening. The fuel burning apparatus is mounted for swinging movement on a pedestal indicated generally as 34 so that the. burner may be swung to and away from the fur.- nace and maybe swung to insert and withdraw the same from the furnace. In orderthat the head portion 28 of the burner can clear the bottom sill, the apparatus as a unit can be tilted as shown in Fig. 3. 1 1 Referring specifically to the drawings, the pedestal 34 includes a flat plate sfi 'which rests upon the floor. The base of the pedestal in the form'of an upright post or pipe 3'7 is carried by a dome 38 which in turn is suitably secured to the plate 36. This dome'is open as at 39 which opens n ing is covered by a cover plate 4.0. The electric and fuel lines for the burning apparatus extend into-the dome 38 through the opening 39. Acollar.

42 is adjustablysecured on the post .37 by set screws. 43.; A bracket 45 is swingingly supported on the post 37 and includes a sleeve 46 which telescopes with the; post 37 and rests in an under cut.

portion of the collar 42. The bracket 45 includes a horizontally extending arm .47 on the outer end of which the burning apparatus 24 is carried.

The outer end of the arm 47 formsa sleeve 48, the opening 49 in which is circular at. the bottom 50. Depending from the base 25 ofthe burning apparatus .24 is a post '53 but oblong at the top 51.

which extendswithin the opening 49 in the sleeve permits a limited pivotal movement of the burn;

Stops, which are spaced from one another and one of which 48 and upon "which the fuel burning apparatus can be oscillated in a horizontal plane and which.

disposed on opposite sides of an ear formed integrally with sleeve 48. These stops 54 are spaced such distances from the ear as to permit a limited oscillation of the burning apparatus. The opposite walls of the sleeve 48 limit the extent of tilting movement of the burning apparatus as shown in Figs. 2 and 3. A washer 56 is held in place by a screw 57 in the bottom of the post to prevent the promiscuous removal of the burning apparatus from the pedestal. The Weight of the fuel burning apparatus to the right of post '53, as viewed in Figs. 2 and 3, is greater than that part to the left of said post; therefore normally the fuel burning apparatus tends to assume the position shown in Fig. 2. However, by pushing downwardly on the motor 26, the fuel burning apparatus 24 can be tilted to the position shown in Fig. 3 so that the head, at the extreme right end thereof, clears the bottom sill 32 of the furnace 20.

In the particular type of fuel burning apparatus herein shown two fuel lines are connected therewith; one for supplying gas to the burner for pilot purposes and the other for supplying oil. These two fuel lines 60 and 61 and an electrical conduit 62, for supplying current to the electric motor 26, extend into the dome 38 through the opening 39 and from the dome pass upwardly through the post 37, sleeve 46, between the flanges 64 of the arm 4'7 and from there lead to the proper mechanism of the fuel burning apparatus.

In order that the fuel burning apparatus 24 can be swung on the pedestal, these fuel lines and the electrical connection must be capableof yielding movement. The electrical conduit 62 is formed of flexible material for this purpose and suitable flexible connections are provided in each of the fuel lines in the pedestal. Referring specifically to Figs. 4 and 5, I have illustrated a fitting 66 for the flexibility of the oil and gas lines. This fitting 66 includes-a coupling 67 which is connected with an inlet pipe 68. This inlet pipe is connected by a coupling 69 with the flexible fuel line 61. Preferably this fuel line 61 within the dome is made of thin wall copper tubing. A coupling '70 having a shank portion 71 telescopes with the upper part of coupling 67 and the extreme upper part of coupling 67 is recessed and the shank portion '71 is undercut to provide a stuffing box containing the packing '72. The coupling '70 is journalled for oscillation in coupling 6'7 and the upper end forms an extension 73 which is connected by a coupling '74 with the flexible oil line '75. Oil flows through thefuel line 61, leading into'the dome 38, through pipe 68, couplings 67, '70 and fuel line '75 direct to the fuel burner. When the bracket 4'7 is swung, it carries with it the pipe '75 which in turn causes the rotation of the coupling '70 in the coupling 6'7.

connected with an upright pipe 7'7 disposed within the post 37. This pipe is held in position by a bracket 78'. A pipe '79 extends longitudinally through the couplings '70 and 6'7 but is spaced therefrom so as to provide a passage 80 for the flow of oil thereabout. A slip connection is provided between the pipe '79 and pipe '77 whereby the pipe '79 may be extended longitudinally of the pipe 7'7. In order to prevent the escape of gas at this slip connection, a packing 82 is provided which is pressed against the interior surface of pipe '79 by a hollow bolt 83 having a screw slot 84 for turning the same. By screwing the bolt 83 downwardly, the packing 82 is pressed against the interior surface of the pipe '79. Thus the pipe '79 can he slid longitudinally of the pipe '77 without the leakage of gas at this joint.

A groove is formed in the pipe '79 which receives a split ring 85 which forms a shoulder for a packing gland 86. The lower part of the coupling 6'7 is recessed to provide a stuffing box containing the packing 8'7 which tightly embraces the pipe '79. Thus it will be seen that when the coupling 67 is forced downwardly the packing will be pressed tightly against the exterior of the pipe '79 to prevent the escape of oil at this joint. The upper part of coupling is recessed and contains packing 89 which is compressed by a packing gland '90 to prevent the escape of oil at this joint. The upper part of pipe '79 is threaded and receives a nut 91. This nut when screwed downwardly forces the gland 90 downwardly to compress the packing 89 against the exterior of the pipe '79. The tightening of nut 91 also causes the packing 89 to force the coupling '70 downwardly so as to seal the joint of the couplings '70 and 6'7 and also forces the coupling 67 downwardly to press the packing 87 against the exterior of pipe '79. An elbow coupling 92 is threaded on the upper end of the pipe-'79 and is connected with the gas pipe 93 and the upper end of this coupling 92 is closed by a plug 94. A screw 95 is threaded in an extension 96 of the coupling 92 and. is utilized for locking the nut 91 in position. When the bracket 45 isswung, the pipe 93 is carried with it causing the rotation .of the pipe '79 with the coupling '70. By removing the plug 94 from the coupling 92 a long shank screw driver can be inserted into the pipe '79 for engagement with the screw slot 84 of bolt 83 for tightening the packingf82; The pipe 93 is connectedby a swivel coupling 98' with the pipe 99 which leads to the pilot burner. This coupling 98 permits the tilting of the fuel burning apparatus to the position shown in Fig. 3 without bending the pipe connections between the burner and the coupling 92. j

By virtue of the present pedestal construction, the burner may be universally used in connection with various types of furnaces. The height of the pedestal can be adjusted to coincide with the height of. the fuel door opening of the furnace. By raising and lowering the collar 42on the post 3'7, the height of the bracket 47 can be varied to suit the particular type of furnace. The flexible oil pipe 61 in the dome 38 permits the raising and lowering of the connection 66 and the slip connection between the pipes 7'7 and '79 permits the longitudinal extension of the gas pipe line. A bracket 101 connected with the interior of the post 3'7 guides the pipe '77 and likewise the connection 66. Access may be had to the interior of the bracket 45 through the top through an opening which is normally closed by a plate 102 held in position by screws 103.

Means are provided for yieldingly holding the bracket 45 in its position in which the fuel burner is disposed within the furnace or when the bracket is swung outwardly from the furnace 90. This means. comprises a pin 105 extending downwardly into the collar 42 and notches one of which is shown as 106, the other notch being removed 90 to the left of view in Fig. 4. The pin 105 resting within the notch 106 normally prevents the turning of the bracket 45, however,

the bracket may be swung causing the lower part of the sleeve to ride on top of the pin 105 but as soon as the lower edge of the notch 106 comes in contact with the pin the bracket will center itself with respect to the apex of the notch 106. M in order to prevent inadvertent swinging of the vided for locking the bracket45 againstrotation.

A lug 106 is formed on the collar 42 which lug receivesan L shapedbolt 107 held in place by a pin 108 through the lower part'thereof. This lug 106* forms a hinge for the bolt so that the bolt may be swung'between two lugs 109 formed-on the sleeve 46. i The outer end of the bolt 107' isthreaded to receive a wing nut 110 'BOTI which when tightened in the position shown in Fig; =7,locks the sleeve46 withthe collar 42 so as to prevent the turning of the bracket 45.

"It will be notedthat the pedestal 34 isfixed atlthe far left hand corner of the plate 36 so as to pro'vide'a wide base to the left and forward of the pedestal 34 to prevent the tilting of the entire apparatus either when it is in its position in the'furnace or removed therefrom.

1r Thus it is apparent from the foregoing that I have provided a pedestal which will, permit the swinging of; the fuel burner into and out of the furnace in which the height ofthe pedestal is also adjustable for universal use for various types of furnaces. i I
